SPECIFICATION forming part of Letters Patent N 0. 609,193, dated August 16, 1898.

.State of New York, have inventedcertain new and useful Improvements in Lamps; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

The subject-matter of this application is Patent No. 28,684, dated December 15, 1896, and also in French Letters Patent No. 262,247, dated April 17, 1897.

My present invention has for its object to provide an improved lamp or lantern particu larly adapted for use on bicycles or vehicles, and has for its object to provide an improved construction whereby a sufficient quantity of air to support combustion will be supplied, and the lamp is not liable to beextinguished either by jars to which it may be subjected or by reason of gusts of air or the blasts incident to its rapid movement.

l-Ieretofore attempts have been made to con- 1 the bottom plate, having the aperture for the struct a small tubular lampor' lantern particularly adapted for bicyclists use, because such lamps and lanterns are best adapted to withstand shocks and gusts of wind without being extinguished; but such attempts have not been commercially successful, for the reason, among others, that it is exceedingly difficult to make a small, symmetrical, and sightly structure of this kind without sacrificing some of the advantageous features of tubular lanterns, unduly heating the air-tubes, and reversing the air-current supplying the flame, or impairing the ability to withstand gusts of wind from all directions (as when the lamp is still) when arranging the parts for the proper burning when the lamp is moved in one direction at speed. Mypresentstructure, however, overcomes all the objections noted and others and fulfils all the requirements of a perfect lamp adapted for bicyclists use; andit consists in certain improvements,which will be hereinafter described, and thenovel features pointed out in the claims at the end. of this specification.

In the drawings, Figure 1 is a side elevation of a vehicle-lantern constructed in ac cordance with my invention; Fig. 2, a plan View of the same with the top removed; Fig. 3, a vertical sectional view on the line was of Fig. 2; Fig. 4, a horizontal sectional view on the line 'y y, looking upwardly; Fig. 5, avertical sectional view on the line 2 z of Fig. 2.

- Similar reference-numerals in the several figures indicate similar parts.

The lamp embodies generally a cylindrical body portion 1, having a goggle or projection 2at its forward end containing a lens or window and at the rear suitable projecting arms 3 for attachment to a suitable holder, either is the top, embodying the ring 4:, detachably connected to the body (by a bayonet-joint or other detachable connection) and having the conical plate 5 and the top plate 6 above it, the openingbetween said plates 5 and 6 at fording an escape for the heated air and products. a

7 indicates the oil-pot, secured to the bottom of the body, with a space between for preventing heating the former.

9 is the burner; 10, the burner-cone; 11,

burner and forming, with the cone and its plate, the air-chamber 12.

13 are windows in the body, and 11 a re movable reflector.

The sides of the body are perforated at 30 to afford a supply of air above the burner, and the vertical plates 31, arranged inside of the body, prevent the air entering said apertures from striking the flame directly.

The lower portion of the body of the lamp beneath the plate 11 is provided with a perforated skirt 50, and the upper portion of the oil-pot is provided with the vertically-extending flange 51, having perforations therein corresponding to those in the skirt 50, and it is arranged to enter the said skirt and to be secured thereto by a suitable fastening, such as a bayonet-joint, the pins 52 on one member entering the angular slots in the other. The upper portion of the burner 9 engages the under side of the plate 11, closing the aperture therein, thereby preventing the entrance of air to the chamber 12 otherwise than through the tubes 15 when the parts are sespring or rigid. At the upper end of the body cured together. The skirt 50 and flange 51, it will be noticed, form a space between the oil-pot and the plate 11, through which air can freely circulate, thereby preventing overheating of the oil-pot, and by this means I am enabled to employ a slip-burner, which is held in place by the plate 11, and there are no joints in the air-circulatin g tubes or chambers necessary to be kept tight.

Arranged around the body of the lantern are several (four in the present embodiment) vertically-extending air-tubes 15, communicating at their lower ends with the air-chamber 12 beneath the burner-cone, and the upper ends of said tubes communicate with the interior of thelamp-body near the top through openings 16, and intermediate the ends of these tubes and on their inner sides next the body are openings 17, which are preferably arranged at the upper portion of the lamp at the upper elbow or the part where they turn toward the body to connect therewith. Encircling the upper portion of the body is an air-director constructed, in the present instance, of two annular dished plates 18, having the outer edges or flanges turned toward each other and forming an open-sided annular air chamber or passage 19. The lower one of the plates 18 is cut away at 20 opposite the openings in the tubes 15, and the vertical dividing or directing plates 21 are arranged in said cut-away portions, extending also vertically across the open portions of the tubes, as in Figs. 3 and 4.

While I prefer to employ four tubes,this particular number is not absolutely necessary; but the tubes should be symmetrically arranged around the lamp-body in such manner that when the lamp is subjected to blasts of air coming from any direction the proper amount of air will be supplied to support combustion and the currents will be balanced. The separation of the tubes from the body of the lamp is desirable, particularly in small lamps, as the tubes are not liable to be heated and the air-currents reversed. It is also eminently desirable that the top and bottom plates of the air-director encircling the body be dished, as shown, in order that vertical currents of air, as those due to the vertical movements of the lamp while in use,m ay cause a sufficient supply to support combustion under all conditions. It is essential that the directorproject sufficiently from the body to allow vertical currents in either direction to co operate with the annular director and be directed into the tubes. This arrangement of air tubes and directors provides for a sut'ficient supply of fresh air beneath the burnercone to produce a brilliant light, while the connection with the upper portion of the body balances the currents to such an extent as to render the light brilliant and steady under all circumstances, no matter whether the lamp is moving forward at speed or is at rest in a strong wind.
